I apologize....I was looking for the old info_at_a_glance_admin_v_1.5 but it has either been renamed or is no longer offered. If anyone knows where I can find this I'd appreciate it.

My guess Craft Magick is that if you undo your install and reverse the order of installing the mods, since the edits to admin>orders replaces sections of code...you may have replaced your edits on the first mod to install the admin notes mod. just a guess.
